Manufacturer:ST Description:TriState The TriState feature puts the LVPECL output driver into a high impedance state, effectively disconnecting the driver from the FOUT and nFOUT pins of the device. A logic 0 is then present on the clock net. The impedance of the clock net is then set to 50Ω by the external circuit resistors. (This is in distinction to a CMOS output in TriState, in which case the net goes to a high impedance and the logic value floats.) The 50Ω impedance level of the LVPECL TriState allows manufacturing In-circuit Test to drive the clock net with an external 50Ω generator to validate the integrity of clock net and the clock load. |
